Gold enrichment in hydrothermal sulfides from the Okinawa ...

Gold enrichment in low-temperature Si-Ba-Fe-rich sulfide, instead of Zn-rich samples. • Low-temperature colloform sulfides and orpiment concentrate majority of gold. • Gold is present as both lattice-bound and submicron inclusions in main carriers. • Dominant Au-HS complexes at near neutral pH probably caused low-T gold enrichment.

Gold Enrichment and the Bi-Au Association in Pyrrhotite ...

High gold contents (to 10.1 ppm, avg 1.4 ppm, n = 34) occur in pyrrhotite-rich massive sulfide samples from the sediment-covered floor of the Escanaba trough, the slow-spreading, southernmost segment of Gorda Ridge. These concentrations reflect the presence of primary gold, formed during high-temperature hydrothermal activity in mounds and chimneys, and secondary gold deposited during sea ...

Oxidation and Secondary Enrichment of Gold Deposits ...

The supergene enrichment of gold in deposits may take place by a simple mechanical process, by chemical means, or by a combination of these. First, the enrichment may be primarily the result of the chemical removal of a large part of the gangue minerals, in which case the gold migrates slowly downward by gravity or is left behind as a residual ...

increase in gold content, as electrum, in gossan weathered from pyritic massive sulfides. Likewise, the concentration of native gold in gossan overlying the Flambeau (Wisconsin) VMS deposit corresponds to a sixfold Au enrichment relative to massive sulfide protore (Ross, 1997). Boyle (1996) lists Au and Ag enrichments in gossans of four ...

Depletion Gilding: An Ancient Method for Surface Enrichment of Gold Alloys ... This enrichment can be due to an addition of gold on the surface, or to a depletion process during which the less chemically stable elements leach out causing the surface composition to change. In both cases, the local percentage of gold is increased consequently.

Crystal habit-directed gold deposition on pyrite: Surface ...

The occurrence of the {2 1 0} shape of pyrite crystals has been used as an empirical indicator for gold enrichment in ore deposits. Such indicating, also called 'typomorphism' in ore mineralogy, was conventionally attributed to environmental factors such as sulfur fugacity and temperature and pressure conditions in the ore-forming hydrothermal fluid.

Supergene (geology) - Wikipedia

In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical weathering.The descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.
